If it expands its range in the Great Lakes, it has the potential to hybridize with the spotted gar (L. oculatus), which is present in Lake Michigan tributaries and Lake Erie proper, and considered nationally threatened in Canada, endangered in Ohio, and of special concern in Michigan.

The shortnose gar (Lepisosteus platostomus) is a primitive freshwater fish of the family Lepisosteidae. It is native to the United States where its range includes the Mississippi and Missouri River basins, ranging from Montana to the west and the Ohio River to the east, southwards to the Gulf Coast .

The shortnose gar is a popular sport fish that can be found from the Gulf of Mexico to the Great Lakes. They are mostly found in the rivers, basins, and tributaries of northeastern states. To catch them, anglers use various methods, such as trolling, spin casting, drift fishing, and fly fishing.

The Shortnose gar primarily are found inhabiting the Great Lakes south towards the Gulf of Mexico. But they are essentially limited at the lower gradient portions of the Mississippi River basin. Where there in the north, would lead to a broad range in the river systems from southern Ohio to Montana that feed the Mississippi.

Short­nose gars spawn in shal­low water among the grass and aquatic weeds and pre­fer grassy sloughs as spawn­ing grounds. Their eggs are large, green, and poi­so­nous to warm-blooded ver­te­brates, in­clud­ing hu­mans (Eddy, 1974). Short­nose gar do not care for their young.

It inhabits calm waters in large rivers and their backwaters, as well as oxbow lakes and large pools. It is a long, slender fish, brown or olive green above and whitish below. It typically grows to about 60 cm (24 in) and is armored by rows of interlocking, rhomboidal ganoid scales.

This gar occurs from the Great Lakes south to the Gulf of Mexico, but is essentially limited to the low gradient portions of the Mississippi River basin. It can withstand higher turbidity than most gars, and is common in calm backwater areas of rivers as well as in lakes and other such waters, frequently where little or no aquatic vegetation is ...

There are three species of Gar that live in the Great Lakes. These include Longnose, Shortnose and Spotted Gar. The Alligator Gar, which is the largest of the gar species, is more commonly found in the southern United States. This puts it nearby the Florida Gar, which can be found in Florida and Georgia.

2012年3月2日 · The shortnose gar is more of a river fish than the longnose, often being found in sreas with current. In larger rivers, they like to hang around the mouths of feeder creeks. They occasionally herd minnows up against steep banks. Few lakes in the northern region support shortnose populations - only two in Minnesota that I'm aware of.
